Hi, I just read the commit from https://go-review.googlesource.com/c/go/+/166960 and it said the reason to use lock-free is because when using mutex "Clearing must zero out the pointer to every object in every Pool to prevent a concurrent slow path from causing all objects to be retained. Since this happens during STW, this has an O(# objects in Pools) effect on STW time." I just can't understand why concurrent Get and clearPool will cause all objects to be retained. Thank in advance for any help!
